DISPENSER CHARGE REGUATING lDEVIGE Filed April 50. 1929 Patented Dec. 2,A193() UNITED STATES i W. FITCH,` OF DES MOINES, IOWA DISPENSERCHARG-E-REGULATING DEVICE Application filed April 30j The obj ect of myinvention is to provide a dispenser charge regulating device of simple,durable and comparatively inexpensive construction. y

More particularly, it is my object to provide a regulating means for thedispensing nozzle of a dispenser of the type shown and described in myco-pending application Serial No. 337,345, filed February 4, 1929.

A further object is to provide such a regulating means consisting of afitting having a plurality of stop shoulders of different heights tocoact with another tting which may be adjusted relative to the rstfitting to engage the desired stop shoulder.

Still a further object is to provide the first litting in theform of anangular member having a stop shoulder on each side thereof andthe secondfitting in the form of a tubularvmember adapted to slide vertically overthe first fitting and having an inwardly eX- tending flange to engageone of the stop shoulders, the flange serving to prevent rotation of thesecond fitting relative to the first fitting.

Still a further object is to provide an anto receive the flange of thesecond fitting, whereby the second fitting may be rotated relative tothefirst fitting for positioning the flange to engage another of the stopshoulders. v

lVith these'and other objects in view my invention consists in theconstruction, arrangement and combination of the various parts of mydevice, whereby the objects contemplated are attained, ashereinat'termore iully set forth, pointed out in my claims, and illustrated in theaccompanying drawings, in which: v

Figure 5 is a similar sectional view on the line 5-5 of Figure 2,showing the parts in a different position.

Figure 6 is a sectional view on the line 6 6 of Figure 4.

Figure 7 is a sectional view on the line 7 7 of' Figure 5; and

Figure 8 is a sectional view of the end olf the Y nozzle shown in Figure2, showingit in a different position. Y On the accompanying dra-wings, Ihave usedthe reference numeral `10 to indicate a cylindrical casing..The casing 10 is provided with a bottom member 12 having a depressedboss 14 at its center; In the boss v14, a socket 16 is formed.

Adjacent the top of' the casing 1() I provide a plurality of inwardlyextendinglugs 18. A top for the casinglO is indicated at 20 andisprovided with a plurality of outwardlyextending lugs 22. The lugs 18Vand 22 may coactV upon rotation of the cover 20, whereby the cover issecured to the casing 10 some-v 'y what similar to a bayonet jointconnection. nular groove around the first fitting adapted Secured to thecover 2O is a fitting A, over which a fitting B telescopically fits. Thefitting B is constrained to move upwardly, due to a spring 24 interposedbetween an upwardly opening socket 26 in the fitting A and in adownwardly openingv socket 28 in the fitting B. Y

Vithin the casing 10 I provide a plunger tube 30, havinga shoulder 32adapted to engage a shoulder 34 formed in the fitting A. Above theshoulder 32 the plunger tube 30 is reduced and its upper end is securedto the fitting B as by a screw-threaded connection.

Within the casing 10 and surrounding the plunger tube 30, I provide afollower disk 36. An enlargement 38 on the lower end of the plunger tube30 prevents removal of the disk 36 from the tube when the cover 20 andthe parts carried thereby are removed from the casing 10. Theenlargement 38 is adapted to coact with the socket 16 in certainpositions of the plunger tube 30.

The foregoingrconstruction is similar to that shown in my co-pendingapplication,

with the exception of the shapes of the fittings A and B, which will nowbe described and which constitute the patentable subject matter of thisapplication. The operation of the dispenser is fully disclosed in myco-pending application, but l will briefly refer to it later in thisspecification.

The fitting A is provided with a plurality of fiat sides 40, the fittingbeing angularshaped and having as many sides as adjustments are desired.Adjacent the lower end of each side 40 l provide stop shoulders 42, 44and 46 with the exception of one side 40, on which l provide noshoulder, for which side, the cover 2O acts as a stop shoulder. The stopshoulder 42 is of predetermined height and the stop s ioulders 44 and 46are progressively higher, as indicated bythe reference characters l), cand CZ, vthe reference character a indicating the lid`20 as a stopshoulder.

The fitting B has a circular interior adapted to just fit over thecorners of the fitting A. The fitting B could therefore rotate on thefitting A except that I provide an'inwardly extending flange 48 tonormally prevent such rotation. The flange 48 may engage the cover 20 orany of the stops 42, 44 or 46, depending on which stop shoulder it ispositioned above, or in other words, which side 40 of the fitting A itengages.

It will therefore be obvious that the fitting B will be positioned onthe fitting A in any predetermined position when the parts areassembled. However, after they are assembled it is desirable to changethe adjustment, which can only be accomplished by rotation of thefitting B relative to the fitting A. The fitting B, however, cannot beremoved from the fitting A, due to the shoulders 32 and 34 engaging eachother. I therefore provide an annular groove 50 at a predetermined pointaround the fitting A so that whenever the flange 48 is in registry withthe groove 50, the fitting B may be rotated.

The sprin 24 normally positions the flange 48 slightly above the annulargroove 50, as clearly shown in Figure 2. When the 'fitting B is presseddownwardly a slight distance so that the lower edge of the fitting B isin alignment with the lower side of the groove 50, as shown in dottedlines in Figure 6, the flange 48 will be in registry with the groove 50and the fitting B may now be rotated to any desired position.

Figure 5 illustrates the fitting B being rotated in the direction ofthe. arrow 52 from the position shown in Figure 4. the flange 48 ofcourse, being in registry with the groove 50.

From the foregoing construction, it will be obvious that the fitting Bwill move downwardly a predetermined distance, depending on which stopshoulder the flange 48 will engage. T he. fitting B will be normallymoved straight down by the barber or whoever is di f.;- pensing thematerial from the casing 10 so that the fiange 48 will prevent rotationof the fitting relative to the fitting and will merely pass the groove50, thereby maintaining the adjustment at which the fitting B is made.

Practical operation I will now describe the operation of the device,wherein it will become obvious why variations are desirable and howvariations are accomplished by the coaction of the flange 48 with thestop shoulders 20, 42, 44 and 46. T he fitting B is manually engaged andforced downwardly, whereupon the enlargement 38 on the plunger tube 30will enter the socket 16. Further downward movement of the fitting B, asfor instance to the position indicated at b when the flange 48 willengage the stop shoulders 42, as shown in Figure 2, will cause thematerial in the casing l() to be forced upwardly through the plungertube 30.

On. the nozzle 54 of the fitting B l provide a rubber cap 56 having aslit opening 58. lhe pressure of the material through the nozzle 54 willcause the ends of the cap 56 to be forced outwardly, as shown in Figure8, thereby allowing the material from the nozzle 54 lto be discharged inthe form of a ribbon indicated at 60.

As the fitting B is released and forced up wardly by the spring 24,there will be a ten dency for the material within the tube 80'to remainstationary, thereby pulling inwardly on the cap 56, which closes theopening 58 to the position shown in Figure 2.

lVlien the flange 48 is adjusted to engage the cover 20 the enlargement38 on the lower end of the plunger tube 30 will be moved downwardly tothe line a. Coaction of the flange 48 with the shoulders 44 and 46 willcause the enlargement 38 to be stopped at the positions c andrespectively. Thus, different quantities of the commodity from thedispenser are ejected from the nozzle 54, depending on the position ofadjustment of the fitting B.

Some changes may be made in the construction and arrangement of theparts of my device without departing from the real spirit and purpose ofmy invention, and it is my intention to cover by my claims, any modifiedforms of structure or use of mechanical equivalents, which may bereasonably in eluded within their scope.
